render method

@override void render(Canvas canvas)

Should render this Particle to given Canvas.

Default behavior is empty, so that it's not required to override this in a Particle that renders nothing and serve as a behavior container.

Implementation

@override
void render(Canvas canvas) {
  canvas.save();
  final current = _tmpVector
    ..setFrom(from)
    ..lerp(to, progress);
  canvas.translateVector(current);
  super.render(canvas);
  canvas.restore();
}
